    driver core: add helper macro for platform_driver_probe() boilerplate

    For simple modules that contain a single platform_driver without any
    additional setup code then ends up being a block of duplicated
    boilerplate.  This patch adds a new macro,
    module_platform_driver_probe(), which replaces the
    module_init()/module_exit() registrations with template functions.

    This macro use the same idea of module_platform_driver().

    This macro is useful to stop the misuse of module_platform_driver() for
    removing the platform_driver_probe() boilerplate.
